DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceramic globule for treating fats and oils, particularly for business and food processing fats and oils, and an apparatus for preventing oxidation of fats and oils using the ceramic globules. The ceramic spherical body placed in the flowing oil to be processed collides with the oil to be processed and vibrates to generate electrons, generates far-infrared rays, and ionizes the oil to be processed by the action of the electrons and far-infrared rays. The present invention relates to a ceramic spherical body which can be activated and a device for preventing oxidation of fats and oils using the ceramic spherical body.

2. Description of the Related Art Fats and oils, especially vegetable oils mainly composed of unsaturated fatty acids, combine with oxygen in the air to proceed with oxidation and generate a bad smell or pungent odor in a relatively short period of time. As the oxidation proceeds further, the oil forms a polymer in which oxygen atoms are crosslinked, and the viscosity and specific gravity increase. Free radicals are also generated by heat, light, trace metals such as iron and copper, and the generated free radicals cause oxidation to proceed in a chain. The oxidation of fats and oils is promoted as the temperature increases. Such deterioration of the oil is a serious problem, especially in a food processing factory using a large amount of vegetable oil, and the use limit of the edible oil is determined by setting the limit of the degree of oxidation to 1 based on the numerical value of the degree of oxidation. .2 to 3,
It has been disposed of as waste oil after replacement. Antioxidants have also been used to prevent oxidation of fats and oils,
In general, the amount of antioxidants that can be added is limited, and the use of antioxidants only delays oxidation during the storage period.Once use by continuous heating is started, the oxidation phenomenon progresses, There was no effective way to stop or delay the oxidation phenomenon.

Further, it has been proposed to use ceramics as an antioxidant for fats and oils (for example, see Japanese Patent Application Laid-Open No.
-330951, JP-A-9-142950, etc.). Japanese Patent Application Laid-Open No. 5-330951 describes a ceramic for preventing oxidation of edible oil obtained by calcining natural zeolite and a powder containing a large amount of calcium such as oyster shell. Is 2.5 mass% of the sum of monovalent alkali metal oxides such as sodium oxide and potassium oxide in the ceramic composition after firing.
A porous ceramic for preventing oxidation of fats and oils as described above is described. Ceramics used to prevent oxidation of these fats and oils are used as generators of far-infrared rays and / or adsorbents such as oxides. In any case, they are porous ceramics. Porous ceramics have the advantage of adsorbing action.Even though they have the effect of removing impurities, they become saturated in a short time due to the impurities adhering to the ceramic surface. Due to the adhesion, far-infrared radiation is blocked in a short time. Therefore, it does not work effectively for a long time.

In addition, these conventional porous ceramics used for preventing oxidation of fats and oils are fragile due to their low sintering temperature, and are liable to crack or chip due to the pressure of the continuously applied oil. It has the disadvantage that cracked or chipped porous ceramics can mix into the processed oil. These porous ceramics do not emit electrons to promote ionization of the fat or oil to be treated. However, since the oxidation of fats and oils is promoted by the generation of free radicals, in order to suppress the oxidation, in addition to shutting off oxygen, it is necessary not to generate free radicals. It is necessary to stabilize by changing to a stable non-radical. Therefore,
If the ceramic itself emits electrons and ionizes to convert free radicals into non-radicals, the oxidation of the fats and oils to be treated can be more effectively prevented.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to dispose electrons in a flowing oil to be treated by placing them in a flowing oil to be treated, whereby electrons are emitted by vibration when the oil and fat to be treated collide with each other to ionize and activate the oil to be treated. By providing a ceramic spherical body that is also a generator of far-infrared rays, it promotes the phenomenon of anti-oxidation, activation, reduction, and precipitation effects of fats and oils, and prevents oxidation of fats and oils after treatment, It has the effects of reducing peroxide value, deodorizing, antibacterial, and reducing carbides, and also prevents the generation of carbides in piping, and is less likely to crack or chip, and is easy to maintain after installation.

) Was immersed for 10 hours and gently stirred every 30 minutes to perform a leaching test. As a result, none of the metals lead, cadmium, chromium, arsenic, mercury, aluminum, silicon, and manganese was detected. The ceramic spheres of the invention have been found to be safe for the human body.

3. Performance Test of Anti-Oxidation Device for Oil and Fat of the Present Invention The above-mentioned ceramic sphere is filled in the anti-oxidation device for oil and fat made of stainless steel of the present invention, and this device is connected to an oil pipe of a food manufacturing plant (Atsuage production line). And rapeseed oil 220
Using a liter, the peroxide value of the oil over time at 180 ° C.,
The oxidation, viscosity and color values were measured. Table 1 shows the measurement results.

[0024]

[Table 1]

From the above results, the acid value of the oil after the treatment for 55.5 hours using the oil and fat oxidation preventing apparatus of the present invention, 2
The values of viscosity (cST) and color (Gardner method) at 5 ° C. are comparable to those of the fats and oils after 16.5 hours when not used, and the peroxide value (meq / Kg) is the antioxidant value of the present invention. When treated with the apparatus, the peroxide value of the oil when not used was remarkably increased, while it was not different from the new oil even after 55.5 hours. From this, it can be seen that the use time of oil was extended about three times by the apparatus for preventing oxidation of fats and oils of the present invention.

The decrease in the peroxide value, acid value, viscosity and color value clearly indicates that the oil treated with the ceramic spheres of the present invention has been activated. In particular, when the ceramic spherical body of the present invention is used for a long time, the deterioration of the peroxide value of the oil is significantly suppressed. Further, by using the anti-oxidation device for fats and oils of the present invention, not only the oxidation of the oil during use could be suppressed, but also the thickness of about 20 mm deposited on the fryer before use. Oxides
The thickness decreased to about 3 to 5 mm in 2 days after use, and it was found that the ceramic spheres of the present invention were also effective in removing the deposited oxide.

Further, the apparatus for preventing oxidation of fats and oils of the present invention
It was found that carbides stuck to the equipment such as the piping connecting the fryer and the filter and the inner wall of the filter could also be removed. That is, immediately after installing the oil and fat oxidation preventing device of the present invention, the oil and fat carbides were closed about 1/3 on the inner wall of the pipe, but after about one month of use, the carbides were almost completely removed. Carbide that had adhered to the inner wall of the filter, which was part of the equipment, was peeled off and the surface of the main body was partially exposed.

From the above results, it was confirmed that the use of the apparatus for preventing oxidation of fats and oils of the present invention was extremely effective in removing carbides in pipes and preventing generation of oxides.

The ceramic spheres for treating fats and oils and the apparatus for preventing oxidation of fats and oils according to the present invention have been described mainly for the treatment of edible oils. However, the fats and oils to be treated according to the present invention are not limited to edible fats and oils, For example, it is suitable for use of heavy oil, kerosene, light oil, gasoline and the like.
